What's the difference between a bench chisel set and a single mortise or carving chisel?

Bench chisels (the 1/4" to 1-1/2" bevel-edge sets) handle most general joinery, paring and cleanup. Mortise chisels are thicker for chopping deep square holes, and carving/linocut tools like the Mikisyo Power Grip are shaped for relief and printmaking work. Most reviewers recommend a bench set as a first purchase, then adding specialty tools as projects demand.
